Indeed, these predictions were borne out in our behavioural results.
Although our fMRI and behavioural results are compatible, they could nonetheless represent different underlying neural mechanisms.
They also used a technique called electroencephalography to show that a brain wave called the N2PC is different in gamers, which fits with their behavioural results.
The behavioural results and event-related potential (ERP) component analyses of the present dataset have been previously reported in Wu et al.23.23
In addition, we aimed to test whether target location would be classified with higher accuracy for category-level vs. exemplar-level non-human target faces, as suggested by the behavioural results, or vice-versa, as suggested by the ERP results.
We speculate that this could be due to the fact that (i) only two target objects were used in each participant and (ii) the majority of AM- trials consisted of incorrect object responses rather than '?' responses (see behavioural results).
More specifically, their comment focuses entirely on the behavioural data and makes no attempt to consider the relationship between the neuroimaging and behavioural results (Hampshire et.al, 2012).
Interestingly, activity in motor spinal cord regions and corresponding twitches and complex movements were not grossly affected by deafferentation, which is in keeping with previous behavioural results, where no effect of deafferentation on the expression and structure of twitches was shown7.
Thus, our behavioural results converge with those of the previous study in two aspects: (1) the increase in generous behaviour was concomitant to an increase in happiness and (2) the magnitude of the increase in happiness was independent of the increase in generosity4.
Behavioural results are depicted in Figure 1.
Our behavioural results show a number of important findings.
